Unmanned underwater vehicles (UUV), also known as uncrewed underwater vehicles and underwater drones, [1] are submersible vehicles that can operate underwater without a human occupant. These vehicles may be divided into two categories: remotely operated underwater vehicles (ROUVs) and autonomous underwater vehicles (AUVs).
To perform this task, the astronauts trained underwater in the Neutral Buoyancy Simulator at the Marshall Space Flight Center. However, due to differences between the design of the mock-up used for training and what they found at Skylab, the astronauts used makeshift tools and redesigned how they would accomplish the task while they were in ...
Replica of the Vostok space capsule, which carried the first human into orbit, at Technik Museum Speyer Mercury space capsule, which carried the first Americans into orbit, on display at the Astronaut Hall of Fame, Titusville, Florida North American X-15, hypersonic rocket-powered aircraft, which reached the edge of space Neil Armstrong, one of the first two people to land on the Moon and the ...
Salyut 1, the first station in the program, became the world's first crewed space station. Salyut broke several spaceflight records, including several mission duration records, the first ever orbital handover of a space station from one crew to another, and various spacewalk records. The program went through various changes.
A Kounotori departing Tanegashima Space Center bound for the International Space Station. Located in Japan on an island 115 kilometres (71 mi) south of Kyūshū, the Tanegashima Space Center (TCS) is the launch site for H-II Transfer Vehicle (HTV), called Kounotori ( こうのとり , Oriental stork or white stork ) , used to resupply the Kibō ...
In the late 1980s NASA began to consider replacing its previous neutral-buoyancy training facility, the Weightless Environment Training Facility (WETF). The WETF, located at Johnson Space Center, had been successfully used to train astronauts for numerous missions, but its pool was too small to hold useful mock-ups of space station components of the sorts intended for the mooted Space Station ...
Apollo 11 Lunar Module Eagle was the first crewed spacecraft to land on the Moon (July 20, 1969).. This is a list of all crewed spacecraft types that have flown into space, including sub-orbital flights above 80 km, space stations that have been visited by at least one crew, and spacecraft currently planned to operate with crews in the future.

Skylab (1973–1974), the first U.S. space station and second overall. In 1971, the Soviet Union developed and launched the world's first space station, Salyut 1. [7] The Almaz and Salyut series were eventually joined by Skylab, Mir, and Tiangong-1 and Tiangong-2. The hardware developed during the initial Soviet efforts remains in use, with ...
